2. Description of the Related Art With the development of information, the use of personal computers in labor management and other affairs such as design, drafting, and document processing has become widespread. What is currently a problem when using a personal computer is that you must operate the keyboard for a long time in a certain posture every day,
Prolonged engagement in this task often causes diseases of muscles and hand nerves.

It is clear that the cause of such diseases is the keyboard, and the design of the general keyboard is fixed, and the operator must simply press the keyboard in a fixed posture, so that the muscle tends to be stiff. It is even said to be a kind of civilized disease. Such diseases are increasing with the spread of personal computers, and are issues that need to be resolved immediately. In view of the above, the present inventors have continued active research and testing, and finally succeeded in developing the present invention, which will greatly benefit those engaged in information processing and other consumers.

[0004]

[Problem to be solved by the invention] The main purpose of the invention is to provide a kind of personal computer keyboard structure, in which the keyboard is divided into two parts, and these two parts can be adjusted in a fan-shaped movement in the horizontal direction. The user can adjust the keyboard to an angle at which the user's hand can be easily operated, thereby preventing the occurrence of occupational diseases.

The second object of the present invention is to provide a kind of personal computer keyboard structure, which divides a keyboard into two parts, and these two parts can adjust a vertical inclination angle, and a user can use the personal computer keyboard structure. The key can be adjusted to an angle at which the user can easily operate the hand, thereby preventing the occurrence of occupational diseases.

[0006]

Accordingly, the structure of the present invention divides the keyboard into two parts, each part having a bottom seat having some arc-shaped grooves and one arc-shaped guide groove, and an intermediate seat connected to the keyboard. The intermediate seat and the bottom seat are pivoted so that the horizontal angle can be adjusted. A small number of guide plates are provided on the bottom surface of the intermediate seat, and function as guides in the arc-shaped grooves of the bottom seat.

A drive lever with a knob is provided on the intermediate seat, a rod and a movable lever are connected to the drive lever, and a fixed frame is pivotally connected to the movable lever. The fixed frame is further pivotally connected to the keyboard seat. Due to the special angle of the driving lever, rod and moving lever, when the user moves the driving lever, a force to move the moving lever outward is generated, which acts on the fixed frame, and the fixed frame pushes up the keyboard seat. Tilt vertically. This inclination angle can be adjusted as needed.

[Outside 1]

A fixed frame 2 having a shape is fixed by attaching both ends below the shaft 22 to a shaft hole 311 of the moving lever 3, and a pin 401 at one end of the rod 40 is connected to a hole 312 at one end of the moving lever 3. Connect to A drive lever 4 which is slightly bent at an appropriate portion is provided, one end of which is connected to the rod 40 by a pin. The other end is divided into both legs, and the middle forms one groove 41. One projection 43 is provided below the drive lever 4 and this projection 43 is provided.
Into the arc-shaped groove 65 on the intermediate seat 6. At the time of fitting, it goes without saying that it is only necessary to insert it through the square hole 650 provided at the end of the arc-shaped groove 65 and move it inside. A knob 5 is provided, and the knob 5 has a hollow head and a knob rod 51 connected to the inner end of the head. A single projection 52 is provided below the knob bar 51, and the projection 52 is formed in the arc-shaped groove 6 of the intermediate seat 6.
It fits inside 2. Slots 50 penetrating to the inside are provided on both sides of the head, the knob rod 51 enters the groove 41 between both legs, and a spring 53 is provided between the ends of the hooks 42 at the ends of the legs and the hollow inside the head. To give the knob 5 elastic elasticity. A shaft hole 13 is provided below one end of the keyboard seat 1, and the shaft hole 13 corresponds to the shaft hole 63 of the intermediate seat 6 and can be pivotally connected through a pin. The shaft hole 12 is also provided at a suitable intermediate position below the shaft hole 12.
And is pivotally connected to a pivot 21 provided at the upper end of the fixed frame 2. The keyboard mounting portion 10 provided above the keyboard seat 1 is used for mounting the keyboard, and the other end of the keyboard seat 1 is a step-like joint portion 11 for adjusting the inclination of the keyboard seat 1 in the vertical direction. It has a structure that can perform. By combining keyboard structures corresponding to this structure, one complete keyboard is constructed.

As shown in FIGS. 2 and 7, when operating the personal computer keyboard of the present invention constituted by the above-mentioned structure, the intermediate seat 6 is integrated with the keyboard seat 1 horizontally at a certain angle in both directions. Move. When moving, the guide plate 64 is
Since it moves along 1,72,73, a calm state can be maintained. Further, the waveform side of the localization block 66 can make a sound by contacting the claw 7510 of the braking section 751 and can be localized at an appropriate angle. At this time, the knob 5 is
As a result, the projection 52 stops at the rear stop hole 622 of the laterally arcuate groove 62 (see FIGS. 3, 4, and 6). When operating the keyboard, by pushing the head of the knob 5 inward, the projection 52 comes off the stop hole 622, moves along the arc-shaped groove 62, and comes to the position of the front stop hole 621. At this time, when the head of the knob 5 is released, the knob 5 returns to the outside by the spring 53, and the projection 52 is fixed to the front stopper hole 621 (see FIG. 4). When the knob 5 is moved to slide the projection 52 in the arc-shaped groove, the moving lever 3 is also moved outward by the rod 40 under the influence of the movement of the knob bar 51, so that the fixed frame 2 is , The keyboard 1 is pushed up, the inclination angle in the vertical direction is maintained, and the operator's hands can use the personal computer in a state most suitable for ergonomics, so that excessive fatigue can be prevented.

When the present invention performs horizontal fan-shaped movement adjustment, the positioning block 66 and the guide plate 64 are
By moving within 1, 72 and 73 and being localized in the guide groove 75, the development angle of the keyboard 1 can be appropriately adjusted. The adjustment of the vertical inclination angle of the present invention is performed by adjusting the protrusion 52 of the knob 5.
By placing the in a suitable position in the arc-shaped groove 62, a desired inclination angle can be obtained.

[0015]

[Effect of the Invention] The fixed frame pushes up the keyboard around the pivot, maintains the vertical inclination angle, and the operator's hands can use the personal computer in the state most suitable for ergonomics. Can be prevented.
